This is one of my favourite cards to get (for the hefty signup bonus)!
I had this when I received 60,000 Membership Reward Points and now the bonus is 75,000 Membership Reward Points!
These Membership Reward Points are convertible 1:1 to Aeroplan or Avios.

I wrote a post that lists all the 10 major benefits for this charge card.
Basically, the sign-up bonus gives you enough points to get (3 free flights round-trip any where in north america or a nice return ticket to anywhere in Europe – includes 2 stopovers), $200 annual travel credit (can be used in 2016 and then in 2017 so this is $400 value), amazing lounge access across the globe, great benefits for insurance, and assorted AMEX perks.
This card has a hefty annual fee $699 – but when you consider the benefits that you get it is well worth it!
